Philly rap-rock duo Chiddy Bang comprise Noah Beresin, better known as Xaphoon Jones (DJ/ producer) and Chidera "Chiddy" Anamege (vocals). The duo met at Drexel University, in Philadelphia, Pennsylvania and this was their first single.

This song heavily borrows from "Kids," the MGMT tune forming the basis of "Adults'" chord sequence and melody.

The duo told Artist Direct the story behind the song:Xaphoon Jones "I've been working with samples as a hip hop producer for awhile. I love the classic soul sound, but with this project, I wanted to do something new that pushes the boundaries of what you hear every day. Chiddy and I are trying to bring back the old vibe of a DJ/producer and MC like Rob Base and EZ Rock. It's definitely that old school fun style with some new school production techniques and rhymes."Chiddy: "I was a freshman in college. Xaphoon played me a slammin' beat that was an MGMT remix. I had no idea who MGMT was, but he had a mash-up with Notorious B.I.G. on it. It was 'Mo Money Mo Problems.' When he played me 'Opposite of Adults,' there was a certain nostalgia to it. It reminded me of my younger days. Lyrically, everybody wants to be a kid forever. No one wants to grow up. That was what I was feeling when I wrote the song—something universal that everybody can dig. When everything is youthful, everything is great. You don't have to worry about anything. That's the life"
